NIOSH Hearing Loss Simulator (HLSim)

About

The NIOSH Hearing Loss Simulator (HLSim) is a software training and communication tool for promoting hearing loss prevention and awareness. It allows a user or trainer to demonstrate the effects of noise exposure on hearing without experiencing an actual noise-induced hearing loss.

Overview

HLSim displays a "control panel" for playing sounds while adjusting the simulated effects of noise and aging. A simulated individual's age (in years) can be entered along with the years of exposure to noise (in A-weighted decibels). The effects are shown visually on the frequency band control panel and sound level display screen while the user listens to the audio playback.
